UARPENTERS VISE.

T at whom it may concern:

Be it known that I, JOHN F. MILLER, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Carpenters Vises; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to IO make and use the same, reference being had to the accompanying drawings, which form a part of this specification, in which- Figure 1 is a sectional elevation of a workbench with my improvements. Fig. 2 is aface I 5 view of the metallic sleeve and flange.

This invention relates to a novel construction of carpenters vises and bench-screws; and it consists in the construction and combination of devices, substantially as hereinafter fully described and claimed.

In the drawings, Ais the work-bench, B its facing, C one leg, and D the movable vise-jaw, all of wood, as usual.

E is the large nut fixed behind leg 0, and

fitting this nutis the vise-screw F. The screw F has the plain shank g and head 71., and,

a next to the head, is formed with the circumferential groove 1', the jaw D being bored out to allow the insertion of screw F. I cast a metallic sleeve, 70, in two parts, to clasp and move freely in groove 1', and provided with the flange I, as shown, having suitable screwholes. I first set the. two-part sleeve into the groove '17, and then insert the screw through tries.

CARPENTERS VISE.

SPECIFICATION forming part of Letters Patent No. 297,282, dated April 22, 1884.

Application filed September 10, 1883. (No model.)

the opening in jaw D till the flange l meets 5 the jaw, to which the flange is then firmly secured by the screws n. Upon now revolving screw F into and out-of the nut E the jaw will be carried in both ways positively. The head h having a bearing endwise on metal, instead of wood, will not cause any wear on the jaw D, and as a consequence the screw and head can be turned out of a billet of wood much smaller in section than formerly. This allows a very considerable reduction in first cost of 5 the screw, as regards both material and labor.

The visejaw D need not be mortised or bored edgewise, and hence will be stronger.

1 I claim as my invention- 1. In a carpenters vise, the combination, with the jaw I), of the screw F, havingshank g, groove t, and head h, and the two-part metallic sleeve k, having flange l secured to said jaw, substantially as described.

2. The combination of the nut E, screw F, having head h, and groove 1; next to said head, and metallic sleeve k, having flange Z, said sleeve fitting in groove 1', and said flange being constructed, substantially as described, for attachment to a viscjaw, as set forth.

In testimony that I claim the ibregoing as my own I have hereto affixed my signature in presence of two witnesses.

JOHN F. MILLER.
